Today I had a realization that I don't need a separate work room to get motivated about my projects (and the work room I got wasn't even motivating me, I rarely used it). I can just show up to my regular work place to work on my own projects instead. You get all the needed mingling, lunches, etc. during the day and you can just keep working on your favorite project throughout the day. This is of course made possible by my 3-day workweek.
